Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN660B-10-06 is based on electrical and mechanical parameter compatibility. The following criteria determine valid substitutes:

Primary Compatibility Parameters:

• Voltage rating: 250VAC (exact match required)
• Current rating: 10A (exact match required)
• Operating frequency: DC ~ 400Hz (exact match required)
• Filter type: Single Phase (exact match required)
• Configuration: Two Stage (exact match required)
• Mounting type: Chassis Mount (exact match required)
• Termination style: Quick Connect (exact match required)
• Operating temperature range: -25°C ~ 100°C (exact match required)

The FN2060B-10-06 meets all primary compatibility parameters and qualifies as a direct substitute for the obsolete FN660B-10-06.

Parameter Comparison

Engineering Selection Recommendations

The FN2060B-10-06 is the direct substitute for the obsolete FN660B-10-06. Both components share identical electrical ratings (250VAC, 10A, DC ~ 400Hz) and mechanical specifications (chassis mount, quick-connect termination, two-stage single-phase configuration).

The FN2060B-10-06 offers the advantage of active product status, ensuring ongoing availability and support. It carries expanded regulatory approvals including CE certification in addition to CSA, ENEC, and UR certifications held by the original part. The substitute meets ROHS3 compliance, representing current environmental standards.

The inductance difference (800µH versus 450µH) reflects design evolution within the FN 2060 series while maintaining functional compatibility for general-purpose EMC/EMI filtering applications at the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the FN2060B-10-06 directly replace the FN660B-10-06 in existing installations?

A: Yes. Both components share identical voltage, current, frequency, mounting, and termination specifications. The FN2060B-10-06 is electrically and mechanically compatible for direct substitution.

Q: What is the significance of the inductance difference between these parts?

A: The FN2060B-10-06 has 800µH inductance compared to 450µH in the FN660B-10-06. Both values are within the design parameters for single-phase EMC/EMI filtering at 10A, 250VAC. The higher inductance in the newer design reflects current filtering technology while maintaining compatibility with the specified operating frequency range.
